I wasn't clear - what I meant was, nothing of the sort WITH BAND
MEMORIES exists. All the MFJ and NIR ones require an experienced
hand at the switches and potentiometers each time you QSY. It would
be very nice to set up once for a session and just bandswitch after
that. If it was stand-alone and not tied to the K2 Auxbus, then you
could also do things like set it up on one AM frequency, null out
a local groundwave station, then QSY to another freq, do the same thing,
and switch back and forth without manually readjusting. What this
would give you is the ability to check two different frequencies for
what are called parallels - two broadcasters in the same network,
which play the same programs, as an aid in IDing what you're hearing.
The folks who DX the AM/BCB regions are really pushing the envelope.

Anyway, my main point was that having memories would be the big =
innovation.
I would think that could be done by using a fine enough resolution on
the PIC control voltages going to the op-amps or whatever the phasing
circuits would require, and using rotary encoders for the adjustment(s)
rather than potentiometers and switches, the way these boxes are now.

I really don't expect Wayne/Eric to buy into this, but it IS something
novel and would be something a non-ham might buy.=20
